Welcome to IT4Innovations documentation pages. The IT4Innovations national supercomputing center operates supercomputers Salomon and Anselm. The supercomputers are available to academic community within the Czech Republic and Europe and industrial community worldwide. The purpose of these pages is to provide a comprehensive documentation on hardware, software and usage of the computers.

In order to use the system for your calculations, you need basic proficiency in Linux environment. To gain the proficiency, we recommend you reading the introduction to Linux operating system environment and installing a Linux distribution on your personal computer. A good choice might be the CentOS distribution, as it is similar to systems on the clusters at IT4Innovations. It's easy to install and use. In fact, any distribution would do.

Note

Learn how to parallelize your code!

In many cases, you will run your own code on the cluster. In order to fully exploit the cluster, you will need to carefully consider how to utilize all the cores available on the node and how to use multiple nodes at the same time. You need to parallelize your code. Proficieny in MPI, OpenMP, CUDA, UPC or GPI2 programming may be gained via the training provided by IT4Innovations.
